Firefox 4 Customisation Notes

bookmark-bar-icons.css

/*
Bookmark bar icons, used on OSX and Windows XP
Because I do not understand why Firefox tries to emulate Safari on OSX. 
I want the exact opposite: Icons and no text. 
This also fixes the default circular hover.

I'm using this style on Windows and OSX as is:
http://userstyles.org/styles/42200/firefox-4-chrome-like-toolbarbuttons

And these on Windows:
http://userstyles.org/styles/45128/always-show-close-button-on-tabs-fireffox-4
http://userstyles.org/styles/45066/firefox-4-increase-url-search-bar-font-size

And this on OSX:
http://userstyles.org/styles/43992/firefox-4-combine-tab-icon-and-tab-close-button

And the others on this page are tweaked versions of existing styles or mine.
